JeJuGATE: The Missing 4 Minutes! The Black Boxes Did NOT Malfunction The Boeing 737 Did - But Why?🚨

The MOST Crucial 4 minutes of the JuJu disaster flight were missing, but it wasn't because the Data and Voice recorders malfunctioned. But it was a much, much bigger problem.

There will still be a ton of evidence for investigators to piece together. The position of switches on the control panel will show how the pilots configured the systems. Yes, that can be determined after even this violent of a crash.
Approximate engine thrust setting can be determined by fan blade scarring, or lack of scarring. Fuel system, electrical, hydraulic systems all have indicators to show how they were operating.
This is a forensical engineering problem, and the recorders help immemsely, but there are many other methods available as well.

Also, a big question is why did they go around? Talk to a couple Southwest pilots that fly 737s and both said if they had a bird strike on the final approach, they would continue with the landing as they are already configured for landing and just radio for the emergency crew to standby

[MrRipper]

Many inaccuracies here. Backup instruments are all electronic and hot wired to the battery. Recorder the same. Landing gear is mechanical. No RAT installed on B737. APU not required and takes up to 2 minutes to start and go online. The B737 has AC and DC power from the engine generators and batteries and inverter. Some systems are always powered via the battery and others get more complicated depending on the use and need for emergency actions.
Dual engine failure is an abnormal procedure in the Boeing checklist. If the pilots had a dual failure and did the 180 back the runway opposite direction the kudos to them. They had a good instructor somewhere in their training. The airplane can land gear up and that reduces taxi in power (shorter landing distance). If the LG were extended the wheel brakes could have been used even with hydraulic system failure. Flap extension is not required but you do need to increase your approach and touchdown speed to prevent stalling.
S. Korea is the land of the not quite right. Some airport bureaucrat probably decided it might reduce maintenance/ costs if they had a protective wall built contrary to ICAO Annex 2 standards. Maybe even got a promotion of that idea. Until it counted.
The same government had access to the aircraft data.

It is believed that both engines were affected by the bird strike. We saw the right engine suffer a compressor stall. The best guess, at this point, is that the left engine suffered damage resulting in smoke being pumped from that engine into the cockpit. Examination of the video of the actual landing shows that the right engine was operating and the thrust reverser on that engine was used. There was no apparent exhaust from the left engine and the left thrust reverser did not appear to be used. It is assumed that the left engine was down. It has been stated that compressed air from the left engine would be fed into the cockpit and the front of the aircraft, while air from the right engine would be fed into the back of the aircraft. Smoke in the cockpit would explain the 180 and quick landing.

People keep asking why the pilot decided to go around. The aircraft made a few maneuvers to try to avoid birds in the air. The landing gear was pulled up and the plane was starting to ascend before the compressor stall occurred. The pilot had therefore already decided to do a go around before the bird strike happened.

The real question is why the landing gear was up during the landing. The belly landing itself appeared to be fine. The reason the aircraft was destroyed was due to a dirt mound topped with reinforced concrete and antenna arrays located within the runoff area. That area is required to be clear. Antenna can be placed there, but they must be frangible. They must break away in the event that an aircraft runs off the runway into the runoff area. Whoever placed that reinforced concrete structure there is responsible for the destruction of the aircraft and the deaths of the people onboard.

in the chicago crash of 1979, when they lost the engine they also lost the cockpit recorder, the pilots failed to start the APU or switch power from the number 2 engine. There is no excuse that 40 years later they havent designed a cockpit recorder that has its own power supply that switches on automatically. Something like a computer UPS, that switches on as soon as main power is lost.
Now we will have to guess what really happened in the cockpit. No matter what evidence they recover, someone will interpret it how they want to interpret it.

[philipbyrnes]

As a pilot I simply don’t understand why after the bird strike they didn’t simply continue their landing and avoid all of this. Why on earth they chose to power on and then attempt “the impossible turn”, the manoeuvre that Absolutely Every new pilot has drilled into them Never to attempt. It’s the same manoeuvre that pilots die from after an engine failure just after takeoff, you Never try to turn around and land back on the same runway, Never. Even if you get turned around and pull a 180, you are suddenly faced with landing on a runway with a tailwind and no engines, it’s almost never going to end well and I can tell you that, having had a complete engine failure on approach to the local circuit and having to make a straight in landing with the wind behind me and a drop off to a creek at the end of the runway that would have been devastating to have hit at speed, and pulling up only about 10 meters (30 foot) from my own personal destruction, I guarantee you this, if I lost everything on final approach for any reason, and I’ve got a dirty great runway sitting right in front of the nose, I am putting that plane on that runway as soon as I can because, any other decision, to me, is really asking for really bad things to happen.

[orlandofanti]

There's one question that doesn't connect: if they lost all electrical power, this looks like they lost both engines. But without both engines how did they had enough speed to abort the original landing, fly over the runway, make the go around, and still land in excess of speed to hit the end of the runway so much fast. So it seems they had power in at least on engine, but somehow this engine wasn't generating electricity. Also we had some other incidents where the plane hit the end of runway in excess of speed and if it was not the concrete wall probably it would be something else. See the TAM accident in Congonhas, 2007.

[simonrochester]

If you look at the flashing beacon on the top and the bottom of the aircraft, they look as though they are not working. That seems to show a major electrical problem. So it seems they had other problems.

[stormspotterkwp]

Really appreciate your commentary. Hardest thing in the world is to admit we just don't know something. We're always trying to fill in that gap, sometimes without justification. Doesn't mean we should stop looking, just means we have to leave it as unexplainable for the time being. Sure looks like that crew flew the heck out of a dead aircraft. I hope that, from the evidence of the butter smooth belly landing helps prevent any scapegoating of the piolets.

A top priority video has just arrived. Love your tenacity Maximus.

[rustyshackleford]

Appreciate your rational calm overview of this mystery accident 😊

[kenmore]

Even though the boxes lost power when the failure happened, they were recording before the failure. That means there probably will be information about what happened to cause the failure. Once electrical power was lost, the CVR is the only one that would really matter anymore. A battery backup on that would be nice.

[kevint]

I’m not a pilot or involved in aviation in any way, so if this question is dumb don’t tear me apart. The video footage indicates that the right engine, while damaged was still functioning. There was heat exhaust and it sounded like it was running. So, isn’t that proof the plane had power? Is it possible that the electrical systems failed and even though there was some power available the plane was u able to use that power?

[kenwhitfield]

Old school flying got the airplane on the ground. Old school accident investigation, if the right investigators are invited to do their job will help solve the question why the crash happened. It won’t be as easy as it they could have with access to the recorder data. But the links in this accident chain should be found, none the less.

South Korea has a culture of saving face above all else. The Korean govt intentionally tampered with the black boxes to remove the last 4 minutes so that either the pilots, or the air traffic controllers, or the government stooge who chose to put that cement wall there could save face. Maybe all 3. Either the pilots said or did something embarrassing or dumb, or the air traffic controller did. I'm betting the pilots shouted at the end 'why the F is there a cement wall here? curse you govt stooge who put this here!'. So they Koreans deleted that from the boxes...

[robertbarnier]

Looks like if the concrete wall wasnt there the pilots would now be considered heroes. Aussie Bob

[bobdevreeze]

Congrats on 100k. Between you and DJ I get all the news I need. I hope the great job continues.

The fact that 2 pple managed to survive means more could have, if not for the ww2 bunker wall

[testboga]

It's no conspiracy, it's exactly as expected for dual engine failure. The recorders require one of the main electrical buses to work because it's a plane from 2009. Still under special excemption. The main battery powers only the emergency systems, a stupid decision by Boeing. When else would you need the recordings if not in such a case?
The pilots experienced dual engine failure or single engine failure and shut down if the healthy engine. The right engine might have had a bit of remaining thrust, but electrical power needs around idle to be available.
